armature ings, one of which is shown at 4-1 near the rear end of themotor, the same being carried by an end plate 4-2, which is shown asbolted to the motor casing 10 by the same bolts 21 which secure theflaring extension 20. This armature shaft is connected by a universaljoint with the propeller shaft 45, which occupies the housing 33 and, atits rear end, is provided with a pinion 46 meshing with the main gear 47of the differential mechanism connected with the live axle sections 48,such parts being shown in dotted lines in Fig. 2. v

The universal joint consists of a yoke 50 secured to the propeller shaft45, a corresponding yoke 51 at right angles to the yoke 50 and connectedwith the armature shaft, and studs 52 and 53 screwing into the yokesmentioned and having inward projections journaled in a ring 55. Theconnection of the armature shaft with the yoke 51 is made by a sleeve 56formed on that yoke which has an angular bore receiving an angularextension 58 of the armature shaft. As shown, the armature shaft and thebore are substantially square in cross section, though other noncircularform may be used if desired.

It will be seen from the above described construction that the armatureshaft and propeller shaft may swing out of alinement with each other byreason of the universal senting a neat appearance.

joint connected with it while the housing head 30 turns correspondinglywithin the spherical socket provided by the motor casing, so that thenecessary independence of movement is provided between the motor and thedriving axles, though the motor is rigidly mounted on the frame. Itwill. be noted also that the propulsive force of the rear wheels istransferred to the body through the. tubular housing 33 and the motorframe. thereby relieving the rear springs of this effect and renderingthe construction more eflicient. The motor casing, together with thehousings, entirely inclose the moving parts from the armature to thelive axle sections, protecting them from dust and pre- This neatappearance is increased by the fact that the motor is supportedhorizontally and in operation the tubular housing 83 is substantiallyhorizontal. It should also be noted that the motor may be very easilyremoved from thetor, when its hangers are released, may be drawn awayfrom the spherical head, the armature shaft slidingout of its socket inthe sleeve 56, with which it has an easy sliding engagement. v,

Having thus described my invention, what I claim is: a

1 In a motor vehicle, the combination, with a frame, of an electric.motor having its axis longitudinal and suspended from the frame in themedian line of the vehicle, said motor having on its end a partlyspherical extension, 0. driving axle, a housing surroundingthe same, atube connected with said housing and having at its ends a partlyspherical extension engaging and making a ball oint with the sphericalextension first mentioned, a propeller shaft in said tube geared withthe driving axle, and a universal means within the spherical membersconnecting the propeller shaft with the ar-' mature.

2. In a motor vehicle, the combination, with a chassis frame comprisinglongitudinal bars, cross bars and intermediate longitudinal barssupported by the cross bars, of an electric motor located centrally ofthe frame and extending in a fore-and-aft direction and suspended byears connected to the intermediate longitudinal bars, said motor havinga partly spherical housing at its rear end, a driving axle, a housingsurrounding the same, a tubular extension from said housing having apartly spherical forward end mounted in the spherical housing of-themotor frame, brace bars leading from the axle housing near its endsforwardly and inwardly and secured at their forward ends to the tubularextension near its forward end, a propelling shaft within the tubularextension, and a universal joint within the spherical members connectingthe propelling shaft with the armature shaft;

In testimony whereof, I hereunto affix-my signature in the presence oftwo witnesses.
